Explain importance of water and roughage …

It is the most important constituent of food. It is essential for life. The human body contains about 70% of water by weight.

• Water is needed by our body to transport digested food to the body cells and chemicals such as hormones around the body.

•  Water is needed by our body to get rid of waste products from the body and to control and regulate the temperature of the body.

• Water also dissolves waste products of the body so that they can be removed through urine and sweat (passing).

•  We get most of the water that our body needs by drinking water, milk, tea, coffee and juice.

A diet which contains the right amount of nutrients, roughage and water are called a balanced diet. Roughage, also known as dietary fibres, is obtained from plants such as fruits, whole grains etc. They do not provide nutrients but add bulk to our food and are essential to our body as they aid in digestion.
